Sorption of Amido Black 10 B onto calcined Zn-Al-NO₃ layered double hydroxide and calcined Zn-Al-CO₃ layered double hydroxide / Mohd Hanisafwan Suhaimi
Layered double hydroxides (LDHs) calcined, denoted as CLDHs, have been shown to recover their original layered structure in the presence of appropriate anions. In the light of this so-called "memory effect", the removal of Amido Black (AB), an anionic dye, from aqueous solution by calcined...
